Help identifying these signatures please

Picked up a signed Raiders logo football that has Paul Tagliabue as the commissioner at the time. Most the signatures I have already ID'd are Los Angeles(or Oakland then LA) Raiders and a few SD Chargers players. This leads me to believe all are players from the 80's/Early 90's. However there are 7 signatures I just can't get a positive ID on if anyone is able to help me out I would appreciate it. Not a need to know as I purchased just to replace a spot on the shelf that was home to my first and most prized signed item, a game football signed by the '76 Raiders, excluding Matuszak who had passed by the time of getting the signatures (which while a cool ball full of different sigs, does not compare at all, and has chargers sigs YUCK!). But still curious as to who the other signatures belong to. Thanks for any help in advance.
